A new method for the estimation of the left ventricular pressure-volume area.
We present a new method for obtaining the pressure-volume area (PVA) as defined by Suga. The method allows calculation of the PVA from pressure and flow waveforms of ejecting beats and requires only one isovolumic ventricular contraction performed at any end diastolic volume.
